Q:What does "billet" mean?
Steelmaking and continuous casting of steel products are mainly used for steel rolling, such as round bar, wire rod, sheet metal and so on
Q:Billet production process
Billets are produced by three process methods:First, through the steelmaking system of continuous casting equipment, from the direct pouring of molten steel billet;Two is the steel ingot produced by the steelmaking system or the continuous casting billet processed by the rolling equipment of the steel rolling system, and the three is the semi-finished product processed by the forging equipment of the steel ingot produced by the steelmaking system.
Q:Use medium frequency furnace (1 million 500 thousand volt ampere) to produce 1 ton cast steel blank, how much kilowatt hour is consumed?
This depends on the intermediate frequency furnace voltage level and inverter efficiency, the general high voltage will save power, generally 550-700 range, details can refer to wcdlsb.net site medium frequency furnace data
Q:Reasons and treatment methods of billet stripping in continuous casting
The main reason for the stripping is that the slab is not uniformly cooled in the mold, which results in uneven thickness of the shell, which results in uneven shrinkage, which leads to the unevenness of the billet. If the mould outlet, two cold area is uneven, the shell support is not full, it will make breaking-off intensified;
Q:The role of carbon content in steels
Therefore, the carbon content determines the use of steel: low carbon steel (carbon content < 0.25%), commonly used as extrusion and stamping materials; carbon steel (carbon content < 0.6%), commonly used as mechanical parts; high carbon steel (carbon content > 0.7%), commonly used tools, tool and mould etc..
Q:What is the difference between carbon three plants and carbon four plants?
The mesophyll cells of carbon three plants are more dispersed, and there are no chloroplasts in bundle sheath cells. Photosynthesis is only carbon three cycle, and the utilization rate of carbon dioxide is low. It usually lives in temperate zone.Four carbon plant mesophyll cells arranged regularly, the formation of two circles of the "ring" and bundle sheath cells, bundle sheath cells have no chloroplast grana, photosynthesis has three carbon cycle and carbon cycle four, higher utilization rate of carbon dioxide, the general life in tropical and subtropical regions.The initial product of CO2 assimilation is not photosynthetic carbon cycle in three carbon compounds 3- phosphoglycerate, but four carbon compounds malic acid or aspartic acid plant.
Q:What does the billet of the steel plant refer to?And steel what is the difference?
The main deformation of reinforced by ribs, binding capacity larger and concrete, so it can better withstand external force. Steel is widely used in all kinds of building structure, especially for large, heavy, light and thin wall structure of high-rise building.
Q:What is the active carbon. What is the difference with the charcoal?
The chemical activation method. The activator of discharged gas, or by activating agent impregnated material, after the high temperature treatment can be activated carbon. The activated carbon has a microcrystalline structure, crystallite alignment completely irregular. The micro crystal (radius of less than 20, a: = 10-10 m), transition hole (radius 20 ~ 1000), big hole (radius of 1000 ~ 100000), so it has great inner surface, the surface area of 500 to 1700 meters / 2 grams.
Q:What is the difference between continuous casting billet and cast billet?
but with high-grade continuous casting line (full protection casting, electromagnetic stirring, liquid stopper control) compared both have a big difference in the crystal, oxidation, surface quality.
Q:What is the difference between steel and billet in the process?
Square is a square steel hollow, with iron produced; but it is a square steel billet is generally solid, forging or casting molding.
